Garrett Boone, Novak Enterprises vice president of operations, needs to replace an automatic lathe on the production line. The model he is considering has a sales price of $294,685 and will last for 15 years. It will have no salvage value at the end of its useful life. Garrett estimates the new lathe will reduce raw materials scrap by $30,000 per year. He also believes the lathe will reduce energy costs by $6,000 per year. If he purchases the new lathe, he will be able to sell the old lathe for $4,500. (a) Calculate the lathes internal rate of return. (Round answer to 0 decimal places, e.g. 25%.)

Internal rate of return

enter the internal rate of return in percentages rounded to 0 decimal places

%

(c) Without doing any calculations, what do you know about the lathes net present value? Net present value will be less than $0, greater than $0, equal to $0.
